Multispectral Object Detection Method Integrating Semantic Correction and Background Suppression
摘要
Abstract
Multispectral object detection suffers from semantic conflicts and background-induced false positives due to modality heterogeneity and complex scenes.This paper proposes the semantic dual collaborative optimization network(SDCONet),which adopts an align-then-enhance paradigm for multi-scale,end-to-end collaborative optimization.To resolve semantic conflicts,it introduces cross-modal semantic correction(CSC),which explicitly measures global cross-modal similarity via normalized correlation maps between RGB and infrared(IR)features.CSC combines k-nearest neighbors(KNN)scheme to select semantically similar fine-grained neighbors for aggregation,enabling dynamic align-ment that couples global dependency capture with local semantic matching,unlike static attention based approaches,mitigates cross-modal misalignment at its source.To curb background false positives,the paper proposes semantic-background con-trastive augmentation(SBCA),which employs a global channel communication(GlobalCC)mechanism to establish cross-modal,channel-wise semantic associations and combines foreground-mask supervision with foreground/background con-trastive learning to strengthen foreground representations while suppressing background noise,overcoming the limitations of unimodal channel optimization.Experiments on the FLIR and KAIST multispectral datasets show that SDCONet improves mAP by 2 and 3 percentage points over the ICAFusion baseline,respectively,while reducing FPR by an abso-lute 1 percentage point on both datasets,demonstrating superior detection accuracy and robustness.关键词
